Within the scope of this invention, "identification" refers to determining the compliance of both a batch of objects and a single object (product) with its unique identification mark. The identification can be effected by applying an identifier (a mark) on a product or by introducing an identifier into the product, e.g. by introducing an information signal into electricity to identify the producer of the electricity or the power 13 transmission line over which the electricity has been supplied from the producer to the consumer.
The term "identification" is used in this meaning throughout the description, including the claims.
Great use is made of the product identification by labels containing 2o bar, symbolic, numeric and alphabetic codes, and by identity transmitters configured as oscillating L.C loops, A code combination of letters, digits, and a tuning frequency of the LC loop represent the identifier which uniquely defines the object.
The aforementioned identifiers and methods of their application on zs objects are described in the specifications to RU patents Nos. 2445780, 274596, 2102246, 2106689, 2112958, and in the description to RU

The prior method provides remote circular control of distributed objects over power transmission lines in emergencies and abnormal situations and may be interpreted as a method for identifying a failure or defaulting operations at the power transmission line or the controlled object.
The prior art, however, is not very reliable in determining the io source, distributor and consumer of electricity, as well as the section of the electrical circuit and the power transmission line over which the electricity is supplied from the producer to the consumer in the electrical power system.
Also known is a method for transmitting a broadcast information I5 over a communication channel, disclosed in ltll application No.94033147 for a method for transmitting a broadcast information, published 20.02.98, which involves grouping the information in a series of information elements and transmitting the same into the communication channel.
2o The prior method provides the transmission of information both to stationary and mobile stations aver one or more communication channels, and may be interpreted as a method far identifying an information transmitter and receiver.
Idowever, in case of using the prior method in power transmission 25 lines, the method is not very reliable in determining the source, distributor and consumer of electricity, as well as the section of the electrical circuit and the power transmission line over which the electricity is transmitted from the producer to the consumer in the electrical power system.
